Abstract
The present invention relates to an aqueous polymer dispersion containing a multistage emulsion polymer particle. The multistage emulsion polymer particle contains a polysiloxane formed in the first stage; a transition layer formed in the second stage; and a polyacrylate formed in the third stage. The transition layer is made of silane coupling agents. The present invention also relates to a method of preparing the aqueous polymer dispersion and use of the aqueous polymer dispersion for preparing coatings.
